Simultaneous PET/MR breast imaging requires the RF breast coil necessary for MR data acquisition to be located in the FoV of the PET detector thus attenuating PET signals and reducing PET quantification accuracy. Integration of a commercial 4-channel RF breast coil on an integrated PET/MR hybrid system resulted in local PET signal attenuation of 4-16% in systematic phantom experiments. Application and registration of a CT-based attenuation map of this coil resulted in successful attenuation correction (AC). First PET/MR studies in breast cancer patients demonstrate successful integration of the RF breast coil into the new application of PET/MR breast imaging.
